Method, apparatus, and program for searching for data

Abstract

A data-search apparatus, method and program are provided which are adapted to search for a plurality of pieces of data, each piece having version data indicating that the piece is derived from certain data. The method includes calculating scores of search results of pieces of data in data groups, each data group being derived from the same data, on the basis of the version data, and determining the order of the search results on the basis of the scores.

1 . A data-search method for searching for a plurality of pieces of data, each piece having version data indicating that the piece is derived from certain data, the data-search method comprising: 
 calculating scores of search results of pieces of data in data groups on the basis of the version data, wherein each data group is derived from the same data; and    determining the order of the search results on the basis of the scores.    
   
   
       2 . The method according to  claim 1 , wherein the scores of the search results of the pieces of data in the data groups are calculated on the basis of a chronological order of versions of the pieces of data, the versions matching a search condition.  
   
   
       3 . The method according to  claim 1 , wherein the scores of the search results of the pieces of data in each data group are integrated to determine the order of the data groups.  
   
   
       4 . A data-search apparatus for searching for a plurality of pieces of data, each piece having version data indicating that the piece is derived from certain data, the data-search apparatus comprising: 
 a calculating unit adapted to calculate scores of search results of pieces of data in data groups on the basis of the version data, wherein each data group is derived from the same data; and    an order-determining unit adapted to determine the order of the search results on the basis of the scores.    
   
   
       5 . A computer readable medium that describes a data-search process for searching for a plurality of pieces of data, each piece having version data indicating that the piece is derived from certain data, wherein the medium causes a computer to execute the data-search process, the computer readable medium comprising: 
 computer-executable instructions for calculating scores of search results of pieces of data in data groups, each data group being derived from the same data, on the basis of the version data; and    computer-executable instructions for determining the order of the search results on the basis of the scores.
